  1. Re:Extra Extra! on Microsoft Patents GPU-Accelerated Video Encoding · · Score: 1

    The TI C80MVP existed back in the early 90s, and had everything that's on a modern GPU, just not in the same quantities.

    Please don't confuse the 'vector' in 'vector processors' (such as some Crays) with the 'vector' in things like 'AltiVec'.

    Real vector processors act on dozens of elements simultaneously, e.g. Crays had 64 64-bit elements in their vectors, some architectures had up to 256 elements that would be acted on in parallel. A measly 4 32-bit elements, or similar, is pathetic, and an insult to real vector processing.

    References? Look up every family of DSP or embedded core in Wikipedia, and look at the uses for it.

    I bet you're the kind of fool who thinks that there aren't 6 ARM cores on my mobile phone (where the sales material only lists one, the main application processor).

    TI never did "vector processors" as such. They did harvard architecture DSPs which would permit streams of data to be squirted in and results to squirted out with very high throughput, even if the latency wasn't brilliant.

    They, however, clearly did 'GPU's. The 34010 was a perfect example of that. However, back in the day we still just called them 'DSP's, as we knew that the digital signals being processed were, most of the time, graphics. Except when they were audio, but you tended to use different DSPs for that (namely the 56k family rather than the 34k family).

    Well, there's a flaw in your premises. The GPUs aren't designed to accelerate 3d rendering, transformation, lighting, and rasterisations.

    They're deisgned to do large quantities of low-precision arithmetic operations on streams of numeric input.

    Being able to do *that* enables them to accelerate 3d rendering. But it also enables them to accelerate video compression. And audio processing. And facial recognition. And asymmetric cryptographic primitives. And ...

    Your humble opinion is clearly correct. It was obvious the first time video cards gained any kind of computational power. How about 1985 with TI's 34010 chip?

    However, your frustration in 1996 was misplaced. Back in 1994/1995 I was *doing* this (or equivalent - H.261 video conferencing) with TI's C80 MVP processor (1 RISC master processor, 4 almost-VLIW DSP cores, and a SDMA unit, all on the same die.)

    Similar things have been done in the UK in the past.

    Presumably as it's a simpler core with fewer optional modules (jazelle, (vector) floating point, thumb modes, ...), with a much lower transister count, smaller cache, less leakage, and lover voltage OPPs, so that at 600MHz it comsumes less than 600/1500 of what the big cortex cores use.

    Regarding your 'I am not aware ...', here's a powertop summary of an mp3 playing on high end ARM-powered mobile phone with no other apps active:

    Freq: 500MHz 3.4%, 250MHz 96.6%
    IRQs in 30s: DMA 3200, [elided] 2150, programable timer 1880, i2c 640
    Core power domain: Off 0%, Retention 0%, Inactive 48%, On 51%
    (other powrdomains like graphics-related stuff: 100% off)
    Total wake-ups 10000 = 333/s, Total IRQs 8000 = 266/s, Timers 2000 = 66/s
    H/W wakeups 100 = 3.3/s

    (OK that was on prototype hardware, but not significantly different from the production version. The kernel was an R&D kernel too, so might have additional logging overhead, but I don't think so, however, I wasn't running it on a jig, it was a live system (i.e. my phone).)

    So I guess you do now know of one.

    Just for reference, this device will play mp3s for longer than a fully-charged iPhone (or what Apple claim in their marketting bumf). So I'm guessing Apple have an even less optimal architecture.

    Note to $EMPLOYER - this is on the device that's already on the market, anyone could have obtained these results.

    The _telco_ world was never one of the 1024 users. Telecomms is all based around the old bitrates of the telephone systems, which were always multiples of 1000 bits per second:

    Historically, audio telephony had a sampling frequency 8 kHz.

    As we went digital, G711 audio channels and ISDN B channels were 64000 b/s for 8-bit audio. Other codecs shrank that to 32000 b/s, 16000 b/s, etc. ISDN D channels were 16000 b/s. ISDN PRI channels were variously 1544000 b/s or 2048000 b/s. All the fat pipes carrying data around, be that SONET (PDH) or SDH use variously
    8448000 b/s, 34368000 b/s, 139264000 b/s, etc., etc.

    All those numbers are multiples of the original 8 kHz.

    So don't blame telephony for the 1024s - they're the least guilty. (Telephony would even include multipliers like 30 or 31, as you'd do the old power-of-2 thing, then reserve space for control or stuffing, or...)
